Emplastus biamoensis

Introducción

Emplastus biamoensis is an extinct ant species from the Late Eocene, known only from a single fossil queen found in the Bol'shaya Svetlovodnaya deposits of Sikhote-Alin, Russian Far East . The species was first described as Emplastus dubius in 2015,but that name was already taken, so it was renamed biamoensis after the former name of the type locality, Biamo . The only known specimen is a gyne (queen) about 5 mm long . Because this species went extinct tens of millions of years ago, no living colonies exist and it cannot be kept in captivity.
